Safety Precautions
NOTICE
It is important to perform daily checks.
Periodic maintenance prevents unexpected
downtime, reduces the number of accidents due to
poor machine performance and helps extend the
life of the engine.
NOTICE
If the oil pump must be replaced, replace it as an
assembly only. Do not replace individual
components.
NOTICE
Do not loosen or remove the four bolts retaining the
fuel injection pump drive gear to the fuel injection
pump hub. Do not disassemble the fuel injection
pump drive gear from the hub. Correct fuel injection
timing will be very difficult or impossible to achieve.
NOTICE
The starter motor can be damaged if operated
continuously longer than 10 seconds while
performing the no-load test.
NOTICE
Do not short-circuit the charging system between
alternator terminals IG and L. Damage to the
alternator will result.
NOTICE
Do not connect a load between alternator terminals
L and E. Damage to the alternator will result.
NOTICE
Do not remove the positive (+) battery cable from
alternator terminal B while the engine is operating.
Damage to the alternator will result.
NOTICE
Do not turn the battery switch OFF while the engine
is operating. Damage to the alternator will result.
NOTICE
Do not operate the engine if the alternator is
producing unusual sounds. Damage to the
alternator will result.
NOTICE
If the engine coolant pump must be replaced,
replace the engine coolant pump as an assembly
only. Do not attempt to repair the engine coolant
pump or replace individual components.
NOTICE
Use a new special O-ring between the engine
coolant pump and the joint. Be sure to use the
special O-ring for each engine model. Although the
O-ring dimensions are the same as a commercially
available O-ring, the material is different.
NOTICE
Remove or install the high-pressure fuel injection
lines as an assembly whenever possible.
Disassembling the high-pressure fuel injection lines
from the retainers or bending any of the fuel lines
will make it difficult to reinstall the fuel lines.
NOTICE
After marking the position of the pump drive gear,
do not rotate the engine crankshaft. Rotating the
crankshaft will cause the fuel injection pump to
become misaligned.
NOTICE
Do not use a high-pressure wash directly on the
alternator. Water will damage the alternator and
result in inadequate charging.
NOTICE
Do not reverse the positive (+) and negative (-)
ends of the battery cable. The alternator diode and
stator coil will be damaged.
